This is an interesting description of how a grid search is done.

In looking at the map, the area surrounding Chase's home bounded by roads (72 Rd to the north, 34 hwy to the east, and other roads to the south and west) is about 2 km by 4 km, or 8 square km which equals about 3 square miles. According to this article, 100 searchers spaced at 20 feet apart would take 9 hours to complete one square mile of search.
So... one would think 300 searchers could cover 3 square miles in 9 hours. Which would mean they could have searched the entire area by now?
It's late, is my math right?
